Sio Moore calls Colin Kaepernick 'chump' on Instagram after Raiders victory (PHOTO)

Is there a more convenient way to celebrate a win over your local rival these days than trolling them on social media?

If you're Sio Moore there isn't.

The Raiders linebacker rubbed his team's 24-13 upset win over the 49ers into Colin Kaepernick's face by posting a photo of himself and the Niners quarterback going nose-to-nose with the caption: "There's a difference between boys and Men... Freakin chump":

There's a difference between boys and Men... Freakin chump

It was the first time Oakland had beaten San Francisco since 2000, so it's easy to understand Moore's vitriol after the Battle of the Bay.

Oh yeah. Moore had one tackle in the game.
